Click to Move -  is a challenge mod that completely removes the standard controls, replacing nearly all functions with mouse controls.

The inventory mechanics have also been completely revamped.
Now the inventory appears as a series of rings, with 9 slots initially available, plus slots for your off-hand and armor. However, if you place a chest in the appropriate slot, you’ll gain 3 additional rings that you can switch between to cycle through items!

How do you get a workbench if there’s no crafting window in the inventory? Just chop down any tree and use any type of log to hit another log, and you’ll get a workbench

Controls:

• Movement - Hold down the right mouse button (you will move in the direction you are facing)
• Jump - Double-click the left mouse button
• Sneak - Double-click the right mouse button
• Open inventory - Middle mouse button
